Airfoil editing - looking for Worldofkrauss.com


I always liked the tools at www.Worldofkrauss.com but the site is not responding. I hope they haven't closed the website.

Does anyone know if they are still on line?

I have tried for days to get onto their site and as soon as I make this post they pop up but it still isn't working properly.

It is a great site to help evaluate the airfoils if you are interested.

World of Krauss doesn't present enough data to make good airfoil choices on there site, nor do they have the full online library of files. We wrote our own code in Matlab that runs xfoil for every airfoil conceivable (well, all those in the UUIC database, some foils aren't listed there but 99% are) and polls the files for the necessary data. Requires ~12 hours of quad-core compute time to do this at just 1 or 2 Reynolds numbers.

Take a look at XFLR5, it has multi-threaded batch analysis and can likely handle your problem.

I was also pretty disappointed to see WofK go down... it may not have been super accurate (Javafoil based if I recall) but it was very handy for quick reference online...

EDIT: Looks like it's back up!

I like them for airfoil comparisons. I am glad they are up again.
